“How do you reckon?” William said, gingerly pushing a gaudy key into one of the door-locks.

“The King-or some limb or other of his government-is coming, in a little while, to steal what I have deposited here. Oh, it is not my property. But is it the King’s?! He has no bloody right to it. If you were to hang your head and let him steal it, the family curse would be confirmed-it would be indelible, then.”

William Ham hauled open the Vault door. Stale air drained out of it. Daniel caught a whiff of sewer-nothing like the Fleet, but enough to stir the memory. “After you, uncle,” said William, sounding rather more serene than he had some minutes earlier.

“No, William, after you! You have precedence. This is your deed. A small one, but a great one. People around the City shall hear of it, and the stock of the Bank shall rise, because of the stand you have made. But more important: your father, if he can see this, is saying to the other departed spirits, this is my son, in whom I am well pleased.”

“Good of you to say so-since I know you don’t believe in any of that!” said William, a bit huskily. Daniel had averted his gaze from the sight of tears filling the pouches under his nephew’s eyes, and so was startled, and almost dropped the lanthorn, when William socked him on the shoulder. “But I do believe in such things, and I say that if my dad’s looking on, why, yours is right there next to him, and couldn’t be happier to see you poking your brand-new King in the eye with a sharp stick!”

A MINUTE LATER DANIEL was alone in the Temple of Mithras, and William Ham was on the other side of the Vault door, locking him in there.

In William’s hip-pocket was a document, freshly signed, in which Daniel took possession of his deposits, and relieved the Bank of all responsibility for them. If nothing else, it would slow the King’s men down for as long as it took them to read it.

Those deposits, of course, were all here and accounted for, stacked on the floor in front of Daniel. The golden cards of the Logick Mill had been sent over from Bridewell in frequent small shipments. After Daniel had visited this place with Solomon Kohan, and become aware of the well-shaft in its floor, he had instituted changes in how the cards were packaged for shipment. He had struck a deal with a cooper near the Vintner’s Yard, and this cooper, Mr. Anderton, had fabricated a run of purpose-built boxes of peculiar design. Most anyone who looked on one of these would guess it was either a snare-drum or a hat-box, about a foot in diameter and half that in height. They were lightweight and not especially rugged, made from splits of soft wood no more than an eighth of an inch thick, steam-bent into hoops, sewed together with rawhide, and sealed with pitch. Each arrived at Bridewell with wood-shavings (a resource produced in superabundance by Mr. Anderton’s arsenal of block-planes and draw-knives). Each had a close-fitting lid. These had been stockpiled at one end of the card-punching shop, handy to the desk where Mr. Ham weighed and accounted for all of the gold. Whenever a batch of cards was complete, and the paperwork all made out, one of these hat-boxes would be pulled off the stack and the lid set aside. Into the bed of wood-shavings would be pressed the stack of cards, all wrapped in paper, and next to it would go a wee purse containing the holes that had been punched out of them. The papers for this batch would be set atop, and finally the lid would be put on, laced down with more rawhide, and sealed all around its rim with tar. Then it was ready for dispatch to the Bank of England.

These containers were nothing like true barrels for strength, water-tightness, or cost. But they would fit down the well-shaft, and they would float, at least for a little while. Which was all that Daniel wanted. As soon as William Ham locked him in to the Vault, Daniel went over and pulled up the plank disk that covered the well-shaft. He was dizzy with a kind of terror that something would have gone wrong, and no one would be there. For a minute his fears were borne out. But then he began to hear voices, and a minute later he observed shreds of light skating and veering around, and finally a candle-flame, directly below. “Ready,” came a voice.

Daniel dropped a hat-box down the shaft. No crashing or splintering noises were returned: only a firm splunk as it was caught by two out-stretched hands, followed by some conversation, and a brief surge of laughter. Then: “Ready!” and Daniel dropped another. It was uneven the first dozen times, with too much conversation and apologizing. Then it seemed as though the men down below had got a bucket-brigade organized, and Daniel ended up being the bottleneck, as he could not seem to ferry the boxes to the hole rapidly enough. In the end Peter Hoxton had to climb up into the vault and assist him. After that, the place emptied out in a very short time.

But by the time the last of the Solomonic Gold went down the hole, voices-angry ones-could already be heard on the other side of the door, and hasty men were rattling the locks and picking curiously at the hasps and the hinges. William had promised to delay as long as he could by being indolent, then argumentative, and finally by pretending he couldn’t find the key; but clearly enough these pretenses were all wearing thin. Worse, Daniel was growingly certain that Isaac was on the other side of that door, and Isaac could pick any lock ever made. After a last look round to make sure no box had been forgotten, Daniel inserted himself into the shaft, and began to seek the ladder’s rungs with his toes. Saturn was not far behind, but he paused at the top of the ladder to fiddle with a bit of rope, and then to set the plank-disk lid into place above his head-closing the door behind him, as it were. That rope still dangled through a small hole bit from the rim of the lid. It led, as Daniel knew, to the underside of a large, ancient-looking crate that rested on the floor of the Vault next to the well-shaft. When Saturn was sure that Daniel had reached the base of the ladder and gotten well out of harm’s way by retreating into the side-shaft, he wrapped that rope around his hands and trusted his whole weight to it. He plunged straight down for about an arm’s length, then was caught short, and had to kick for a rung. The crate had shifted over and, or so they hoped, covered the lid. This might or might not buy them a few minutes of extra time, depending on how closely the Vault was searched.

Saturn pulled the ladder down and carried it with him as he followed Daniel to the bank of Walbrook. The stream’s course was now marked out, spottily, by a series of candles. One or two men could be heard sloshing downriver. Saturn here discarded the ladder and then followed Daniel down the current, snuffing out candles as he went, and both of them keeping an eye peeled for hat-boxes that had gone astray.

A few minutes’ wading brought them to the orifice that served as cellar-drain for St. Stephen Walbrook. Daniel went through first, crawling up it on his belly until rough hands grasped his, and drew him out in one long heave. He could not see very well for a minute, because there was suddenly too much light coming into his eyes. But he could smell the mineral tang of fresh mortar, and he knew from the calluses on those hands that they must have belonged to masons. There was a minute of bother trying to get Saturn up through the drain, which turned to hilarity when he popped loose; then he jumped to his feet and shushed them all furiously, saying that he had heard voices echoing down Walbrook from the Bank, and he thought one of them might be an angry Sir Isaac.

Daniel could see now. There was quite a crowd there in the crypt under the church: a mason and two younger assistants, two coopers from Mr. Anderton’s company, Daniel, Saturn, and a pair of mudlarks who had been part of the bucket brigade. As well as a very old and bent-over chap, in good clothes and good humor, seemingly fascinated by the hole in the floor whence so many novelties had just emerged.
